Imitated normal hard book cover



Feb. 9, H965 Filed May 18. 1962 L M 15 w W nit States Patent 3,169,029IMITATED NORMAL HARD BOOK COVER Morris 1. Margolis, Brewster, N.Y. F. M.Charlton (30., 443 W. 15th St., New York 11, NY.) Filed May 18, 1962,Ser. No. 195,719 2 Claims. (Cl. 281-29) This invention relates tobookbinding, and particularly to covering paper bound books.

So called paper bound books have been made for many years but initiallywere limited to notebooks and the like. As competition and costincreased, cloth binders made prices of cloth bound volumes tooexpensive for the average book published. With the tremendousimprovements in the plastics industries, plastic sheets and paper sheetswith plastic coating are available which are particularly adapted foruse as book covers. However, in almost all instances, such covers arequite flexible and lack thickness of body, unlike cloth bound books.

Accordingly, an object of this invention is to provide a cover for apaper bound book that simulates a cloth cover.

Another object of this invention is to provide a paper book cover thatis rigid and has substantial thickness.

Still another object of this invention is to provide a unitized paperbook cover that has improved cover hinges comparable to cloth bookcovers.

These and other objects and advantages will become apparent to thoseskilled in the art by referring to the following description and theaccompanying drawings wherein:

FIGURE 1 is a perspective view of an unfolded paper book cover inaccordance with the invention;

FIGURE 2 is a perspective view of a book with the cover of FIGURE 1, oneleaf of the cover being open;

FIGURE 3 is an enlarged sectional view of the open cover portion ofFIGURE 2 taken on line 3-3;

FIGURE 4 is a sectional view of the book of FIG- URE 2 taken on line4-4;

FIGURE 5 is a perspective view of an unfolded modified paper book covermade in accordance with the invention;

FIGURE 6 is a sectional view of the back part of a book with the coverof FIGURE 5.

At the outset, it should be understood that the term paper book cover isused in its generic sense to mean a book cover of paper or cardboardthat is either finished or not with a plastic layer. This term is alsoconsidered to denote a cover of plastic or of a paper or cardboard layeradhered to a layer of plastic.

Now referring to the drawings, a paper book cover 10 is made of asubstantially rectangular sheet with upper and lower surfaces 11 thatare parallel to one another. The cover 10 is symmetrical about a centralback panel 14. Fold lines 15, 17, 19 and 21 are indicated byconstruction line in FIGURE 1 on both sides of panel 14. Betweenprogressive pairs of the aforementioned fold lines, on both sides ofback panel 14, are binding panels 16, outer front and back panels 18,inner front and back panels 20, and tab panels 22 at the ends of thecover 10. The outer front and back cover panels 13 extend past the topand bottom edges 11 to provide tabs 12 which are folded on lines 13alined with edges 11.

As shown in FIGURES 2 to 4, tabs 12 are folded along lines 13 againstthe inner surface of the outer cover panels 18. Inner front and backcover panels 20 are folded along lines 19 and are glued or cemented totabs 12. The tabs 12 space panels 18 and 20 to provide a air pocket 23which may be filled if desired. The tabs 22 may be folded oppositely topanels 20 along lines 21 to provide spacers as shown at the upperportion of the book of FIG- URES 2 and 4, may be cemented to the bindingpanels 16 (not shown) or may be cut off along lines 21, as shown at thelower portions of the book of FIGURES 2 and 4.

Binding panels 16 are folded relative to back panel 14 along lines 15 toprovide a U-shaped channel to receive the backs of the pages P of thebook and to be attached thereto.

Referring now to FIGURES 5 and 6, a modified cover 10A has no bindingpanels 16 nor tab panels 22 thus the cover sheet is out along lines 21to provide end edges 25. Tab panels 12 and cover panels 20 are folded inthe same manner as heretofore described. Edges 24 now overlie fold lines17. Outer cover panels 18 are folded along lines 17 relative to backpanel 14 which is now the only panel to be attached to the pages P ofthe book.

While this invention has been described with particular reference to theconstruction shown in the drawing, it is to be understood that such isnot to be construed as imparting limitations upon the invention, whichis best defined by the claims appended hereto.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A unitized paper book cover made of a single substantiallyrectangular sheet with parallel upper and lower edges, comprising:

(a) a U-shaped back panel having a pair of spaced binding portions to beconnected to the pages of a book;

(b) folds on both sides of said back panel providing hinges;

(c) a pair of cover panels connected to said back panel by said hinges;

(d) each of said cover panels having an end edge fold spaced from one ofsaid hinges providing an outer cover portion therebetween and an innercover portion substantially equal in size to said outer cover portion;

(e) each outer cover portion having spaced fold lines alined with theupper and lower edges of the sheet;

(1) a pair of tabs connected to each outer cover portion by the spacedfold lines and folded back against the inner surface of the outer coverportion along such fold lines;

(g) the inner cover portions folded back along the end edge fold linesto the outer cover portions and the tabs connected thereto;

(h) the inner cover portions being cemented along their edges and spacedby the tabs from the outer cover portions to provide closed air pocketsin the front and back book covers;

(i a pair of fold lines each at the end of one of the inner coverportions spaced from one of the end edge fold lines and overlying one ofthe hinges; and

(j) a pair of tab panels connected by the fold lines overlying thehinges to said inner cover portions and being cemented to the bindingportions within the U-shaped back panel.
